[Patch] Fix compilation of Debian backend under GCC 4.0.2 on Ubuntu

[Karl Hegbloom <hegbloom pdx edu>]

It would not compile, giving warnings about "no previous prototype" for
several functions declared in the "interface_parser.h" header.  It turns
out that they need to have "void" explicitly written into the prototype
now.  I also added 'static' to several functions that did not appear to
be part of that module's interface; take it or leave it.
